      Public observing night at Elgin I spent a lot of time observing carbon star V Aql. I set my own user object with J2000 coordinates, but I was puzzled, why 10″ SCT with goto Autostar II is always off.  Day later I found that Autostar most likely is using coordinates RA/Decl for current time with current precession. One can find such coordinates at https://stellarium-web.org/ 

      I have learned from Randy about Garnet star (mu Cep). It has a nice warm color and compared to V Aql is more yellow. Here is why V Aql has temperature 2800 K, Garnet star has temperature 3551 K.

        A somewhat blurry Saturn taken last night (9-30) with a new ASI camera (183MC) and my 10 inch SCT. Seeing conditions were fair to poor.

            Processing recent images of Jupiter and Saturn using a sequence of free programs including PIPP, AutoStakkert3, Registax 6. There are good tutorials online such as this one https://www.youtube.com/watch?v=zQYbtzsnQ3E

              Is Eagle Bluff available this weekend?  Anyone thinking of going out observing?  It looks like it may be the last good day until next year… maybe.  Friday looks pretty good.  Saturday may be starting to cloud up a bit more, but looks to be warmer.

                  Jim, Saturday may be better.  Looking at the Clear Sky Chart and hourly forecasts, they are showing Saturday as clearer than Friday.

                    I called yesterday Eagle Bluff general number and left message (at I believe option 6) to switch off parking lights. No answer so far 🙁

                      The December Sky and Telescope mag motivated me to get out early this morning and see if I could observe and photograph “The First White Dwarf” star in 40 Eridani; the latter is a triple star with the B component a white dwarf.
                      In the attached photo I used the 10 in SCT and Orion 6.3 M pixel camera with a 8 second exposure. The bright component A is quite overexposed (but did have a nice yellow color) and component C was quite faint (11.2 mag). Visually I could barely see the white dwarf B (9.5 mag) and seeing conditions were poor unfortunately.

                          If we don’t hear anything about Eagle Bluff, I’ll probably head to Keller.  Unless some can turn the light off at Root River?

                            So what’s everyone think?  Not as clear as I thought it was going to be.

                              yea, my situation has changed anyway so i won’t make it. i hope the wind dies down…

                                Well Jim the wind didn’t die down and so I stayed home where I can partially block the wind with my observatory dome. Seeing conditions otherwise weren’t too bad. A bit obsessed with 40 Eridani I did go out and obtained another picture, this time with the ASI 186MC camera (shown below).

                                  Bob, well done images of the 40 Eridani! Thanks for bringing attention to the White Dwarfs – https://rochesterskies.org/40-eridani-b/
